Definitions:
------------

	KEY_NAMELEN 	max. size of keyword name 
			has to be synchronized with midas_def.h !!
	KEY_MAXENT	initial max. no of global keyword entries
	LOC_MAXENT	initial max. no of local keyword entries
	KEY_FACT	average no. of bytes per keyword


Structure KEY_ALL:
------------------

	ORIGIN		indicates, if ST interfaces are called from the Midas
                        monitor (= 1) or from an application running
			inside MIDAS (= 0) or completely outside (= -1)
	SYSNO		No. of system keyword entries
	GLOBENT		max. no of global keyword entries
	GLOBDAT		max. space for global keywords in bytes, calculated
			as GLOBENT * KEY_FACT
	GLOBNO		No. of last global keyword entry in use (0, 1, ... )
	GLOBEND		Last 4-byte word used for global keywords (0, 1, ... )

        global and local keywords are stored bottom up; local keywords begin
        at limit of global keywords

	LOCENT		max. no of local keyword entries
	LOCDAT		max. space for local keywords in bytes, calculated
			as LOCENT * KEY_FACT
	LOCNO		No. of last local keyword entry in use (GLOBENT, G+1, )
	LOCEND		Last 4-byte word used for local keywrds (GLOBDAT, G+1, )
	

	KEYNAMES	pointer to KEY_STRUCT array
	KEYWORDS	pointer to data buffer (as double)


Structure KEY_STRUCT:
---------------------

	IDENT		Name + type of keyword:
			IDENT[0]-[14] = keyword name 	
			IDENT[15] = keyword type	
			IDENT[16] = A,B,...,J to indicate level 1,...,10
			           for local keywords
	BYTELEM		No. of bytes per element of keyword
	NOELEM		No. of elements connected with keyword
	LEN		Length in bytes of elements connected with keyword
	OFFSET		Offset of keyword values within data block
	FRPAD		No. of bytes needed to pad in front to get to valid
			offset in data space for given data type 
	MODTIME		last time this keyword was updated 
			in seconds from 1. Jan 1970
	KLOCK		locking key, if = 0 not locked
	UNIT		units (not implemented yet)
	

	KEYALL.KEYWORDS is an unstructured data block (all data types are
	intermixed) and is pointed to by:

	IWORDS		for int values
	RWORDS		for float values
	DWORDS		for double values
	CWORDS		for char values
